python - Destroy everything inside a window outside of function Tkinter -

in code below destroy inside window root when gamebutton button pressed, other things happen way button run function. when perform self.destroy outside of main class, nothing deleted, there way around this?

from pil import image, imagetk tkinter import tk, label, both,w, n, e, s, entry, text, insert, toplevel ttk import frame, style, button, label import tkinter import callingwordlist difficulty = ""  class mainmenuui(frame):      def __init__(self, parent):         frame.__init__(self, parent)             self.parent = parent          self.initui()      def initui(self):          self.parent.title("type!")         self.pack(fill=both, expand=1)          style = style()         style.configure("tframe", background="black")                  logo = image.open("type!.png")         typelogo = imagetk.photoimage(logo)         label1 = label(self, image=typelogo)         label1.image = typelogo         label1.place(x=342,y=80)         label1.pack()          self.pack(fill=both, expand=1)          gamebutton = button(self, text="main game", command=lambda: main2(self.parent,self))         gamebutton.pack()         gamebutton.place(x=344,y=200,height = 80,width = 176)          tutorialbutton = button(self,text="tutorial level")         tutorialbutton.pack()         tutorialbutton.place(x=344, y=300 ,height = 80,width = 176)          quitbutton = button(self, text= "quit",command=self.parent.destroy)         quitbutton.place(x=344, y=400,height = 80,width = 176)  def main2(root,self):     self.destroy     app = maingameui(root)     root.mainloop()  class maingameui(root):     ....  def main():      root = tk()     root.geometry("860x640+300+300")     app = mainmenuui(root)      root.mainloop()  if __name__ == '__main__':     main() 

you aren't destroying in function. @ code:

def main2(root,self):     self.destroy     app = maingameui(root)     root.mainloop() 

notice first line in function trying destroy everything. code self.destroy - notice lack of parenthesis. aren't calling function, referencing it. add parentheses call it: self.destroy().

you have problem in you're calling function destroys widget calls function. however, function enters endless loop (mainloop()), button command never return. i'm not entirely sure happen here, you'll sort of error. bottom line is, calling mainloop button command not idea.

since structuring app such app frame (rather root window) don't need restart event loop. when destroy mainmenuui widget, event loop continue run. there's no need restart it.
